So I looked up Google's documentation and it turns out sliders do have to be mirrored: https://material.io/design/usability/bidirectionality.html#mirroring-elements https://material.io/design/components/sliders.html#usage As for the implementation, @broulik mentioned it would be better to use `controlRoot.mirrored` for mirroring and `controlRoot.visualPosition` for value. I couldn't come up with something that would work well, but if anyone has ideas I'll change the current code.
